IMPROVEMENT IN CURTAIN-FIXTURES.

Specification formingpart of Letters Patent No. 187.422, dated February 13,1877; application filed r April 13, 1876.

To all whom it may concern Be it known that I, HERMAN SEEHAUSEN, of Memphis, in the county of Shelby and State of Tennessee, have invented certain new and useful Improvements in Curtain Fixtures, of which the following is a speciiicathis specication.

Figure l is a sectional view. Fig. 2 is an end view. Figs. 3 and 4 are views of detached parts. Fig. 5 1s an end view. Fig. 6 is a front view.

A is the sheave, preferably formed of two disks of sheet-metal. These disks are dished, as seen in the drawing, and when placed together are secured to the end of the curtainroller B by a screw, C, which screw forms the journal of the roller. On the said screw are tted the following-named parts: First, a disk or metallic washer, E, which is secured to said i screw, so that it cannot turn independently oi leather washer, H, similar to the washer F,

comes next. rhen follows a piece of flat spring metal, J, composed of a central disk and radial arms, which arms press against the side of the sheave A near its rim. This di'sk J fits loosely upon the screw C. Lastly, beneath the spring J is a coiled spring, K, which surrounds the screw G, and which is compressed between the spring` J and the dished side of the sheave A.

The operation of this devicel is as follows: When the cord is pulled to elevate the curtain, the screw B rotates in the bracket provided for it, and the notched disk G is held fast from rotating by a projection formed on the bracket. The friction, then, between the several disks of leather and of metal--all kept It is obvious that the following modification Q.

ofthe arrangement ol" the washers and springs may be made without departing from the principle of this invention, viz: The disk E l may be extended out to form a disk-spring like the spring J, and be substituted for it, still retaining the square hole through its een# ter, when one of the leather washers will rest directly against the dished side of the sheave, the coiled spring K and a plain washer being interposed or not, as desired.

The journal part of the screw C may be formed of a brass collar, if desired, which can be renewed when worn out, and the disk E may be secured upon the screw G by a square shoulder formed thereon, or by any other suitable means. It is obvious, also, that one side of the bracket supporting the journal C may be employed to take the place ofthe washer E.

The object of using leather washers, or some equivalent material, is to obtain"gretrriction with a given amount oksirface, and less wear of surface in contact.

Having thus fully described this curtainfixture as of my invention, I claiml. The combination, with the hoistingsheave of a curtain-roller, of the spring-disk J, provided with arms j, in combination with disks `E Gr, washers F H, and screw G, all arranged, constructed, and operating substantially as set forth.

2. The coiledspring K, placed between the sheave A and spring-disk J, substantially in the manner hereinbefore described, and for the purposes set forth.

In testimony that I claim the foregoing as my own I affix my signature in presence of two witnesses.

HERMAN SEEHAUSEN.
